Speaker size

There are speakers in the Dash. Anyone know what size they are? I can't seem to get any info about these. I want to replace them because they don't work. If I am doing something wrong let me know, I just discovered they were there (is there a switch or someway to make it work). May sound stupid but, a stupid question is on that goes unasked. Here's a pic:

I believe they're 5 1/4.

Yo....check out www.crutchfield.com - although their prices are high, there selection is great, and you pick your car type and they tell you what the OEM speakers are...After you do your research at crutchfield, you can go buy them cheaper somewhere else like:

5.25 fit in that narrow dash?

You could only fit a 3" in that spot. :grinno:

that section is for tweeters which are real small usually round "speakers" but are more like the opposite of subs instead of playing really deep low sounds they are for the really high pitched sounds, and if you get some nice polk or boston accoustic ones youll hear a humongous difference in how defined and clean the music is dont let the size trick you, they are about like 2 -3 inches or so in diameter as stated before.
